This is the only vid that shows the right way to weld a plastic radiator tank !! The radiator tank plastic generally has a high load of fiberglass in it. When repairing high stress areas (like mounting brackets) I like to add in material taken from another tank and work it into the top layer. It's best to get material from fresher tanks as the material seems to get brittle over time and high temperature use. Nice tool and the feed hole is very good because the fed rod is fully melted when injected into the repair. It's tricky to get the material all melted in a pool without it.

How about using Permatex RTV sealant? It is automotive grade for up to 400F.

Thanks for the video! Just used a torch to heat a screwdriver. It was able to melt and mix crack on hose elbow. Fingers crossed. Ha ha. Thanks again!

[@scottb7600]

Good deal! Elbows are tricky as they undergo bending stress as well as the stress from heat and pressure. You repair might hold, but my guess is you will need to add some filler rod and some stainless steel mesh to make it a permanent repair.

[@raynic1173]

Broham, it's been 2yrs. since your posted comment. How's the repair holding up?

[@britishbluetess]

using a soldering iron to melt in plastic cable ties into the cracks will do the same job

[@polyvance]

In principle, it's simlar, but not if the cable ties are not made of the same kind of plastic. Even if they were the same, the weld wouldn't be quite as reliable.

[@mikek4610]

britishbluetess hahahaha...said the shade tree hack

[@deankay4434]

As an ASE Master Tech since 1978, I too can tell you that plastic cable ties are not all created equal. Many have a low temperature cheaper plastic that will fail in high temperature conditions likes found in under hood from engine and 220 - 264 degree heat. I have used factory recommended convoluted tubing in concert with OEM cable ties that do not snap or become brittle over time. So if you purchase the more expensive wire ties that have a temperature rating published with the product, you may get away with that type of repair. Ask a radiator “Repair Shop” that fixes hard to find tanks.

[@larryhale7618]

It is much easier with less cost and tools to repair with a JW Weld epoxy kit. I have repaired radiator solder joints with epoxy resin kits. They last forever. The key is to dry the surface and degrease it by wiping the surface the alcohol. Then roughen the surface with sandpaper. Mix the kit and apply. You can use it in an hour, although I wait 4hrs.

[@scottb7600]

that may work on the aluminum fins, but it will not produce a reliable repair on plastic radiator housings.

Do you mean JB weld, not JW?

[@efrensaclolo7021]

I will use JB weld and get the same results,thank you for the video a much better way.It is good.

[@scottb7600]

JB weld will not hold for very long, it doesn't withstand the expansion and contraction of the radiator well and it doesn't bond incredibly well to nylon.

[@darrenkamalu9047]

About to try the JB Weld approach, but this is a great way to go if you have the tool.

Can I buy the rod that was hit in the cheeks from anywhere, or is it for radiators?

[@polyvance]

All of our welding rods can be found here: www.polyvance.com/Welding-Rod-List/ You need to make sure the plastic welding rod matches the plastic you are repairing. Here, the radiator we repaired was nylon, so we used our R06 nylon rod.

Mine is the same tank like that plastic one on the side but it's metal how can I do it?

[@fookutube501]

My radiator connector(as shown on your video) broke clean off .I try to save the broken bit in the hose but couldn't .So basically i can't connect the hose,does this mean i have to replace the whole radiator ?.Can you replace only the top plastic part?........

[@wacio]

You could replace the plastic radiator end only - but the problem is to get the part and to mount it so the seal with core doesn't leak.

[@HavinFunNDeezLastDayz]

I just broke my cousin's and I need to fix can buy a radiator for someone else's car when mine needs to be fixed as well. I was trying to get starter bolt off and pressed down on radiator hose and plastic broke from radiator. Now that's another job. Trying to get it sealed back

Can this be done with a soldering iron and pvc pipe? As in melt the pvc onto the radiator crack

[@scottb7600]

no. A: A soldering iron is not the correct shape for pushing plastic around without creating pin-holes. B: PVC is not the same material as the radiator, so it will not stick.

No. This is a nylon plastic welding rod. Radiators are made out of nylon. We fuse the base plastic and welding rod together by smearing the welding rod into the melted radiator plastic, as seen in the video.

Absolutely not. Its the same plastic the radiator is made of, which is (PA) Nylon.

[@lizardking8388]

I would have used a wire mesh on both of these repairs.

[@scottb7600]

I wouldn't have hurt as it does help prevent pinholes, but on these examples it wasn't needed.

[@lizardking8388]

@@scottb7600 It also adds stress relief; unless you completely penetrated the plastic all the way to the other side, there is still a fracture there weakening the area.

[@scottb7600]

@@lizardking8388 yes, and that's where making the v-groove deep enough comes in.

[@lizardking8388]

@@scottb7600 Not trying to troll you here. The v-groove is very much needed; I would have done that as well, but unless you see the inside after doing the groove, there is no way of knowing for sure if you went deep enough. My point was just that with an added mesh, you'll be 100% sure that even if you didn't groove it deep enough, it would be at least as strong as if you did. For the small amount of added effort for a job that's relying on holding back some very high pressures; I think it's a no brainer.

[@scottb7600]

@@lizardking8388 No, I understand your argument, no offense taken. But sometimes the extra material added on top of the repair thickens the repair area sufficiently that the stress riser of not quite welding 100% through is more than compensated for. Just two different methods to get to the same result. I did do this repair, but I'm with you, if I did it, i also would use mesh, but I also tend to be one of those more is better types. One person here fixed their radiator about five years ago, no mesh, its still holding fine, but again, if it were me, I put mesh in everything that holds liquids in or out ( Boats, water tanks, fuel tanks, radiators, etc.) unless its crosslinked PE, where you can't embed mesh even if you wanted to.

[@scottb7600]

Abraham did you know parts of some plastic radiator housings come welded from the factory? Welding is welding, whether its done by a machine or you at home, both are just as reliable as long as the right filler rod and temperature is used. I wouldn't hesitate taking my family anywhere with a hole or crack that I welded shut on my radiator. My wife's car has an intake that I welded 3 years ago, its just fine...same plastic.
